3 0

Explanation:

rand() function is used to generate random integers between the range 0 to RAND_MAX.So if we divide the the rand() function by RAND_MAX the value returned will be 0.

You cannot do RAND_MAX + 1 the compiler will give error integer overflown.

To generate an integer with a range.You have to do like this:

srand(time(0));

int a=-1*(rand() % (0 - 5245621) +1);

cout <<a;

This piece of code will return an integer within the range 0 to -5245622.

{ //main method

   public static void main(String args[]){

      // create an object of Scanner class to read input

      Scanner s = new Scanner(System.in);

      // string array to store name of candidates

       String name[] = new String[5];

       // int array to store vote count of candidates

       int v_count[] = new int[5];

       double p = 0;

       int i = 0, sum = 0, high =0, win = 0;

for(i = 0; i < 5;i++)

       {

          System.out.print("last name of Candidate " + (i+1) + ":");

          // read name of Candidate

          name[i] = s.next();

          System.out.print(" number of votes received: ");

          // read vote of Candidate

           v_count[i] =s.nextInt();

if(v_count[i] > high)

              {

                  // highest vote

                  high = v_count[i];

                  win = i;

              }

              // total vote count

           sum +=v_count[i];

       }

     // printing the output

      System.out.println("\nCandidate\tVotes Received\t% of TotalVotes\n");

       for(i = 0; i < 5;i++)

       {

           // % of vote of each Candidate

           p =(v_count[i]*100)/sum;

           // print the output

          System.out.println(name[i] + "\t\t" + v_count[i] + "\t\t\t" +p);

       }

       // print the total votes

      System.out.println("\nTotal Votes:\t" + sum);

      // print the Winner of the Election

Write an algorithm and draw flowchart to print 30 terms in the following sequence
valina [46]

Answer:

/*

I don't know what language you're using, so I'll write it in javascript which is usually legible enough.

*/

console.log(buildSequence(30));

function buildSequence(maxVal){

   maxVal = Math.abs(maxVal);

   var n, list = [];

   for(n = 1; n < maxVal; n++){

       /*

        to check for odd numbers, we only need to know if the last bit

        is a 1 or 0:

       */

       if(n & 1){ // <-- note the binary &, as opposed to the logical &&

           list[list.length] = n;

       }else{

           list[list.length] = -n;

       }

   }

   return list.implode(',');
